IMPROVEMENT IN THE PREPARA'I'IQN OI AERATED DRINKS POR MEDICINAL FUR- POSES.

.ll'he Schedule referred to inthese Letters Patent and making part of the same.

13 all whom 'it'may concern Be it known that we, PETER H. VANDER WEYDE,

" M. D., and JOHN MATTHEWS, J r., both of the city-0f New York, in the county of New York, in the State of New York, have invented a new and useful Improvement in the Preparation of Artificially-Aerated Drinks, for Medicinal and Hygienic Purposes; and we do hereby declare that the following is a full and exact description thereof.

Our improvement consists in incorporating, in artificially, aerated drinks, nitrous oxide, or laughing-gas, under pressure, in the same way that, thus far, carbonic acid alone has been introduced; but as pure water does not dissolve this gas in such a quantity as it dissolves carbonic acid, and a large quantity in solution is very desirable; and as we also discovered that the solvent power of water for these gases increases by the addition of sugar, of gurn,of gelatine, of albumen, of

alcohol, and of many other organic substances, we do As nitrous-oxide water has proved to be a remedial agent for rheumatism, neuralgia, 860., its introduction in the trade, in suitable packages, will be a benefit,

medicinally considered, but it will be also a preferable substitute for the exciting alcoholic drinks, as its slight intoxicating efiects pass off in a few minutes.

What we claim, and wish to secure by Letters Patent, is, p

l. The combination of a solution of sugar, or its equivalent, in water, with nitrous oxide, or laughinggas, for medicinal purposes. 7

2. The combination of a solution of sugar, or its equivalent, in water, with nitrous oxide, or laughinggas, carbonic-acid gas, and any flavoring-ingredient, forming an exhilarating substitute for the injurious, irritating alcoholic drinks.

In witness whereof, we have. signed our names, in presence of two witnesses. JOHN MATTHEWS, J R.
